Meet the oceans\u2019 unsung hero.
Human activity is having a huge impact on the world\u2019s oceans - global warming, pollution from fish farms and damage from the fishing industry are all threatening some of the oceans most important ecosystems.
But one creature might be able to help. The humble sea cucumber \u2013 an animal in the same family as starfish that looks like a lumpy sausage and lives on the ocean floor.
